Description

Technical Field

[0001] The utility model relates to the field of food processing machines, in particular to a food processing machine capable of reducing resonance. Background Art

[0002] Among the food processors in the prior art, one common type is a split structure, including a main unit and a mixing cup assembly that are separately arranged, the mixing cup assembly including a mixing cup and a mixing blade disposed in the mixing cup, the main unit including a machine base and a motor disposed in the machine base, and the motor drives the mixing blade to rotate. In order to facilitate the transmission connection and electrical connection between the main unit and the mixing cup assembly, an upper connector connected to the mixing blade is provided at the bottom of the mixing cup, and a lower connector connected to the motor is provided at the upper part of the machine base, and the upper connector is detachably connected to the lower connector, and at the same time, the main unit and the mixing cup assembly, and the upper coupler assembly on the mixing cup assembly are electrically coupled with the lower coupler assembly on the main unit.

[0003] In order to achieve the centering of the upper connector and the lower connector, radial limit is performed between the main unit and the mixing cup assembly, but a certain degree of freedom is retained in the circumferential direction, and a certain angle can be rotated, resulting in the following disadvantages in the prior art:

[0004] 1. The blending cup and the main unit only have circumferential limiters, which allows the blending cup to produce a certain rotational deviation in the circumferential direction, resulting in deviation in the connection between the upper and lower coupler components, which can easily cause the blending cup to resonate.

[0005] 2. The mixing cup and the main machine have circumferential limiters, and the connection position deviation of the upper and lower coupler assemblies is relatively small. However, due to the radial gap between the mixing cup and the main machine, the mixing cup deflects around the coupler position, causing the upper and lower connecting heads that transmit power to be misaligned, resulting in abnormal resonance of the machine. Utility Model Content

[0006] The utility model aims to provide a food processor with reduced resonance, so as to solve the problem in the prior art that the rotation of the stirring cup induces resonance, resulting in a large vibration amplitude of the food processor.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a food processing machine with reduced resonance, comprising a main machine and a stirring cup assembly, the stirring cup assembly comprising a stirring cup and a stirring knife arranged in the stirring cup, the main machine comprising a machine base and a motor arranged in the machine base, the motor drives the stirring knife to rotate, an upper connecting head connected to the stirring knife is provided at the bottom of the stirring cup, a lower connecting head connected to the motor is provided at the upper part of the machine base, the upper connecting head is transmission-connected with the lower connecting head, a limiting ring extending circumferentially is provided at the upper part of the machine base on the radial outer side of the lower connecting head, a limiting groove extending circumferentially is provided at the bottom of the stirring cup on the radial outer side of the upper connecting head, the limiting groove is limitedly matched with the limiting ring, and the upper connecting head and the lower connecting head are aligned and positioned up and down, and a circumferential limiting structure for limiting the circumferential rotation of the stirring cup relative to the machine base is provided between the bottom of the stirring cup and the upper part of the machine base.

[0008] After adopting the above technical scheme, the utility model has the following advantages: in this embodiment, the limiting cooperation of the limiting ring and the limiting groove increases the contact area between the stirring cup and the machine base, so that the stirring cup and the machine base limit each other, which helps to quickly and accurately complete the upper and lower centering positioning of the upper connector and the lower connector, reduce the up and down vibration generated when the stirring cup is working, and at the same time limit the left and right swing of the stirring cup, ensure the concentricity between the stirring cup and the motor, reduce the possibility of abnormal resonance of the machine, which is beneficial to reduce the generation of noise, improve the connection reliability between the main machine and the stirring cup assembly, and ensure the transmission connection between the upper connector and the lower connector to drive the stirring blade to rotate, so as to achieve stirring and crushing of materials.

[0009] By setting a circumferential limiting structure between the machine base and the blending cup, the rotation of the blending cup relative to the machine base can be further limited, thereby enhancing the stability of the blending cup installed on the machine base and reducing the resonance caused by the deviation of the blending cup. This is conducive to making the food processor more stable during operation, reducing the resonance caused by rotational deviation, improving the user experience, and helping to improve the stability of the food processor and extend its service life.

[0010] Furthermore, the circumferential limiting structure includes a limiting boss provided on one of the limiting groove and the limiting ring and a limiting rib provided on the other, and the limiting rib limits the limiting boss on both circumferential sides of the limiting boss. By adopting the above-mentioned technical scheme, the limiting boss and the limiting rib increase the contact area between the machine base and the mixing cup, provide a stronger anti-rotation effect, increase the anti-rotation limit points, reduce the vibration caused by circumferential rotation, and help improve the overall stability of the food processor. The limiting rib is located on both circumferential sides of the limiting boss. When resonance occurs, the limiting rib clamps both sides of the limiting boss, and limits the limiting rib along both circumferential directions at the same time, reducing the vibration of the limiting boss, thereby reducing the deviation of the mixing cup, reducing the resonance caused by the deviation, and ensuring the stability of the food processor. In addition, the structural processing and design of the limiting boss and the limiting rib are simple, which helps to reduce the production cost. When the limiting groove and the limiting ring are installed in coordination, the circumferential limiting structure further limits the circumferential rotation of the mixing cup relative to the machine base, thereby enhancing the stability of the food processor during operation.

[0011] Furthermore, the inner side wall of the limiting ring is provided with a radial recess, and limiting ribs are provided on both circumferential sides of the radial recess, and the limiting boss protrudes radially and is inserted into the radial recess. With the aforementioned technical solution, the limiting boss is inserted into the radial recess, and is further limited by the limiting ribs, so that the connection between the mixing cup and the base is more stable, and the resonance caused by the rotation and displacement of the mixing cup can be effectively limited, which helps to improve the stability and reliability of the food processing machine. The limiting ribs help to improve the matching stability between the radial recess and the limiting boss, provide a certain buffering effect, help to reduce the occurrence of vibration, and further help to reduce the wear between the limiting boss and the radial recess.

[0012] Furthermore, the limiting boss is in the shape of a circular arc protrusion, and the radial recess is in the shape of a circular arc depression. With the aforementioned technical solution, the limiting boss and the radial recess are both set in the shape of a circular arc, so that the fit between the limiting boss and the radial recess is tighter, and the shape of the circular arc can better distribute stress, reduce the risk of deformation caused by stress concentration, and improve the structural strength of the circumferential limiting structure, which helps to strengthen the limiting relationship between the limiting boss and the limiting rib, reduce the relative rotation between the mixing cup and the base, and thus reduce the resonance phenomenon caused by rotational deviation. The processing of the circular arc protrusion shape and the circular arc depression shape is relatively simple, which helps to reduce production costs and processing difficulty.

[0013] Furthermore, an upper guiding bevel is provided on the outer side of the arc protrusion, and a lower guiding bevel is provided on the outer side of the limiting rib, and the upper guiding bevel cooperates with the lower guiding bevel. With the above-mentioned technical solution, the cooperation between the upper guiding bevel and the lower guiding bevel provides a precise guiding effect, which is conducive to the rapid and accurate insertion of the limiting boss into the radial recess, and can easily install the mixing cup assembly on the machine base, which is conducive to the centering and positioning of the upper connector and the lower connector, and is also conducive to reducing the friction between the arc protrusion and the limiting rib, extending the service life of the circumferential limiting structure, effectively reducing the occurrence of resonance, and improving the user experience.

[0014] Furthermore, a heat-insulating sleeve is provided at the bottom of the blending cup, and the limiting groove is provided in the heat-insulating sleeve. The aforementioned technical solution can effectively reduce the influence of the heat generated during use on the limiting groove, prevent the limiting groove and the limiting ring from deforming, thereby causing the gap between the blending cup and the base to be too large, affecting the stability of the blending cup assembly, and ensuring that the limiting groove and the limiting ring fit closely, which helps to reduce the occurrence of resonance during use. In addition, the heat-insulating sleeve can prevent the heated blending cup from scalding the user, ensuring the user's safety, wherein the heat-insulating sleeve has a certain heat resistance and can withstand high temperatures during use.

[0015] Furthermore, a shock-absorbing pad is provided on the machine base, and the limiting ring and the shock-absorbing pad are an integrated structure. By adopting the above-mentioned technical solution, the shock-absorbing pad can effectively absorb and buffer the vibration and impact generated during use, so that the machine base and the mixing cup are in flexible contact, the damage to the machine base and the limiting ring is reduced, the vibration of the mixing cup group and the machine base is reduced, and it is beneficial to improve the stability and service life of the food processor. The limiting ring and the shock-absorbing pad are an integrated structure, which simplifies the overall structure, helps to reduce the number of parts, reduces production costs and assembly difficulty, reduces the direct effect of vibration and impact generated during the use of the food processor on the limiting ring, helps to improve the stability of the limiting ring, improves the limiting accuracy of the limiting ring, and helps to extend the service life of the food processor.

[0016] Furthermore, a cup body bracket is provided at the bottom of the mixing cup, the heat insulating sleeve is fixed to the cup body bracket, and the cup body bracket is provided with limiting convex surfaces that cooperate with the inner circle of the limiting ring at intervals along the circumferential direction. With the above-mentioned technical solution, the mixing cup is positioned in the circumferential direction by the cup body bracket and the inner circle of the limiting ring, and the limiting convex surface is pressed against the inner circle of the limiting ring, providing a more stable support and positioning effect, so that the center of the mixing cup is aligned, reducing the resonance caused by rotational deviation, and enhancing the stability of the mixing cup. Moreover, the cup body bracket is arranged at intervals along the circumferential direction, which can provide more uniform and stable support, and further ensure the stability of the mixing cup.

[0017] Furthermore, the limiting ring is provided with a notch, and the circumferential limiting structure on the machine base is located in the same radial direction as the notch. By adopting the aforementioned technical solution, by arranging the notch and the circumferential limiting structure on the machine base in the same radial direction, the two ends of the mixing cup in the same radial direction are limited, and the mixing cup is limited in both the clockwise and counterclockwise directions of the circumference, thereby further reducing the rotation of the mixing cup and ensuring the stability of the food processor.

[0018] Furthermore, the circumferential gap between the limiting boss and the limiting rib is L, L≤0.3mm. With the aforementioned technical solution, the smaller circumferential gap L ensures a tighter fit between the limiting boss and the limiting rib, ensures better upper and lower centering positioning of the upper connector and the lower connector, and can better withstand the vibration and impact generated during use, thereby improving the stability of the food processor and reducing resonance. The tight fit between the limiting boss and the limiting rib can prevent debris or liquid from entering the circumferential gap, which is beneficial to extending the service life. If L>0.3mm, the circumferential gap L will be too large, the limiting boss and the limiting rib will not fit tightly, and a good stabilization effect cannot be achieved for the mixing cup, resulting in a more obvious resonance caused by the rotational deviation of the mixing cup, resulting in poor stability of the food processor and a louder noise.

[0019] Furthermore, an upper coupler component is provided at the bottom of the blending cup between the limit groove and the upper connector, and a lower coupler component is provided between the limit ring and the lower connector of the base, and the upper coupler component is electrically coupled to the lower coupler component. The aforementioned technical solution is adopted, and by providing an upper coupler component and a lower coupler component, the connection between the blending cup component and the base is further strengthened to form a positioning point that is centered up and down, which is conducive to reducing the rotation of the blending cup and can effectively reduce the vibration generated during use. In addition, the upper coupler component is electrically coupled to the lower coupler component, which can realize the electrical coupling between the blending cup and the base, realize the transmission of electrical signals, realize automatic and intelligent control, and realize precise control and monitoring of the blending process.

[0020] Furthermore, the circumferential limit structure position on the base is located in the same radial direction as the lower connector and the lower component of the coupler, and the circumferential limit structure position on the base and the lower component of the coupler are located on both radial sides of the lower connector. With the aforementioned technical solution, the circumferential limit structure position, the lower connector and the lower component of the coupler are located in the same radial direction, forming three positioning points on a straight line, which more effectively prevents the mixing cup from rotating relative to the base and strengthens the circumferential rotation limiting effect. The circumferential limit structure position and the lower component of the coupler are respectively located on both radial sides of the lower connector, preventing the mixing cup from deflecting with the lower connector as the fulcrum, limiting the rotation direction and range of the mixing cup, ensuring that the mixing cup is tightly and stably connected to the base, and helping to reduce resonance.

[0030] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0031] like Figures 1 to 6 As shown, the utility model provides a food processing machine for reducing resonance, comprising a main machine 1 and a stirring cup 2 assembly, the stirring cup 2 assembly comprising a stirring cup 2 and a stirring blade 3 arranged in the stirring cup 2, the main machine 1 comprising a machine base 11 and a motor arranged in the machine base 11, the motor driving the stirring blade 3 to rotate, an upper connecting head 21 connected to the stirring blade 3 is provided at the bottom of the stirring cup 2, a lower connecting head 111 connected to the motor is provided at the upper part of the machine base 11, the upper connecting head 21 is transmission-connected with the lower connecting head 111, a circumferentially extending limiting ring 112 is provided at the upper part of the machine base 11 on the radial outer side of the lower connecting head, a circumferentially extending limiting groove 22 is provided at the bottom of the stirring cup 2 on the radial outer side of the upper connecting head 21, the limiting groove 22 is limitedly matched with the limiting ring 112, and the upper connecting head 21 and the lower connecting head 111 are vertically aligned and positioned, and a circumferential limiting structure for limiting the circumferential rotation of the stirring cup 2 relative to the machine base 11 is provided between the bottom of the stirring cup 2 and the upper part of the machine base 11.

[0032] In this embodiment, the limiting cooperation of the limiting ring 112 and the limiting groove 22 increases the contact area between the stirring cup 2 and the machine base 11, so that the stirring cup 2 and the machine base 11 limit each other, which helps to quickly and accurately complete the upper and lower centering positioning of the upper connecting head 21 and the lower connecting head 111, reduce the up and down vibration generated when the stirring cup 2 is working, and at the same time limit the left and right swing of the stirring cup 2, ensure the concentricity between the stirring cup 2 and the motor, reduce the possibility of abnormal resonance of the machine, which is beneficial to reduce the generation of noise, improve the connection reliability between the main unit 1 and the stirring cup 2 components, and ensure the transmission connection between the upper connecting head 21 and the lower connecting head 111 to drive the stirring blade 3 to rotate, so as to achieve stirring and crushing of materials.

[0033] By providing a circumferential limiting structure between the machine base 11 and the blending cup 2, the relative rotation of the blending cup 2 can be further limited, thereby ensuring the concentricity of the blending cup 2 and the machine base 11, reducing the deviation between the blending cup 2 and the machine base 11, and ensuring the centering of the upper connecting head 21 and the lower connecting head 111, thereby enhancing the stability of the blending cup 2 installed on the machine base 11, reducing the resonance caused by the deviation of the blending cup 2, and helping the food processor to be more stable during operation, reducing the resonance caused by rotational deviation, and also helping to reduce noise, improve the user experience, help to improve the stability of the food processor, and extend its service life.

[0034] In order to further reduce the resonance caused by the offset between the base 11 and the blending cup 2, in one embodiment, the circumferential limiting structure includes a limiting boss 23 provided on the limiting groove 22 and a limiting rib 113 provided on the limiting ring 112, and the limiting rib 113 limits the limiting boss 23 on both sides of the circumference of the limiting boss 23. The limiting boss 23 cooperates with the limiting rib 113 to reduce the matching clearance between the limiting ring 112 and the limiting groove 22, increase the contact area between the base 11 and the blending cup 2, provide a stronger anti-rotation effect, increase the anti-rotation limit point, reduce the vibration caused by circumferential rotation, ensure better centering of the blending cup assembly and the base 11, reduce the offset between the blending cup assembly and the base 11, thereby reducing resonance, which is beneficial to reducing noise and helping to improve the overall stability of the food processor. The limiting ribs 113 are located on both sides of the limiting boss 23 in the circumferential direction. When resonance occurs, the limiting ribs 113 clamp both sides of the limiting boss 23, and limit the limiting ribs 113 along both sides of the circumferential direction at the same time, thereby reducing the vibration of the limiting boss 23, thereby reducing the displacement of the mixing cup 2, reducing the resonance caused by the displacement, and ensuring the stability of the food processing machine. In addition, the structural processing and design of the limiting boss 23 and the limiting ribs 113 are simple, which helps to reduce the production and manufacturing costs. When the limiting groove 22 is installed in conjunction with the limiting ring 112, the circumferential limiting structure further limits the circumferential rotation of the mixing cup 2 relative to the machine base 11, thereby enhancing the stability of the food processing machine during operation. At the same time, after the limiting boss 23 and the limiting ribs 113 are aligned up and down, the limiting groove 22 and the limiting ring 112 can be installed in conjunction, and circumferential limiting and radial limiting can be achieved at the same time, which is more conducive to the centering assembly of the mixing cup assembly and the machine base 11, and is conducive to reducing resonance.

[0035] Alternatively, in another embodiment, the limiting boss 23 may also be arranged on the limiting ring 112, and correspondingly, the limiting ribs 113 are arranged on the limiting groove 22, and the limiting ribs 113 limit the limiting boss 23 on both sides of the circumference of the limiting boss 23, and the specific setting position can be adjusted according to actual conditions.

[0036] Among them, the circumferential gap between the limiting boss 23 and the limiting rib 113 is L, L≤0.3mm, for example, L can be set to 0.1mm, 0.15mm, 0.2mm, 0.25mm or 0.3mm, etc. The smaller circumferential gap L ensures a tighter fit between the limiting boss 23 and the limiting rib 113, ensures better upper and lower centering positioning of the upper connector 21 and the lower connector 111, and can better withstand the vibration and impact generated during use, improve the stability of the food processor, reduce resonance, and the tight fit between the limiting boss 23 and the limiting rib 113 can prevent debris or liquid from entering the circumferential gap, which is conducive to extending the service life. If L>0.3mm, the circumferential gap L will be too large, the limiting boss 23 and the limiting rib 113 will not fit tightly, and the mixing cup 2 cannot achieve a good stabilization effect, resulting in a more obvious resonance caused by the rotation deviation of the mixing cup 2, resulting in poor stability of the food processor and a louder noise.

[0037] Among them, the inner side wall of the limiting ring 112 is provided with a radial recess 1121, and the circumferential sides of the radial recess 1121 are correspondingly provided with limiting ribs 113, and the limiting boss 23 protrudes radially and is inserted into the radial recess 1121. The limiting boss 23 is inserted into the radial recess 1121, and is further limited by the limiting ribs 113, so that the connection between the mixing cup 2 and the base 11 is more stable, which can effectively limit the resonance caused by the rotation and displacement of the mixing cup 2, and help to improve the stability and reliability of the food processing machine. The limiting ribs 113 help to improve the matching stability between the radial recess 1121 and the limiting boss 23, provide a certain buffering effect, help to reduce the occurrence of vibration, and help to reduce the wear between the limiting boss 23 and the radial recess 1121.

[0038] Among them, in order to further strengthen the limiting effect of the radial recess 1121 on the limiting boss 23, the limiting boss 23 is in the shape of a circular arc protrusion, and the radial recess 1121 is correspondingly in the shape of a circular arc concave. The limiting boss 23 and the radial recess 1121 are both set in the shape of a circular arc, so that the cooperation between the limiting boss 23 and the radial recess 1121 is tighter, and the shape of the circular arc can better distribute the stress, reduce the risk of deformation caused by stress concentration, and improve the structural strength of the circumferential limiting structure, which helps to strengthen the limiting relationship between the limiting boss 23 and the limiting rib 113, reduce the relative rotation between the stirring cup 2 and the base 11, and thus reduce the resonance phenomenon caused by rotational deviation. The processing of the circular arc protrusion shape and the circular arc concave shape is relatively simple, which helps to reduce production costs and processing difficulty.

[0039] In order to facilitate the insertion of the limiting boss 23 into the radial recess 1121, in one embodiment, an upper guiding bevel 231 is provided on the outer side of the arc protrusion, and a lower guiding bevel 1131 is correspondingly provided on the outer side of the limiting rib 113, and the upper guiding bevel 231 cooperates with the lower guiding bevel 1131. The cooperation between the upper guiding bevel 231 and the lower guiding bevel 1131 provides a precise guiding effect, which is conducive to the rapid and accurate insertion of the limiting boss 23 into the radial recess 1121, and can easily install the stirring cup 2 assembly on the machine base 11, which is conducive to the centering and positioning of the upper connector 21 and the lower connector 111, and is also conducive to reducing the friction between the arc protrusion and the limiting rib 113, extending the service life of the circumferential limiting structure, effectively reducing the occurrence of resonance, and improving the user's experience.

[0040] In order to prevent the blending cup 2 from overheating and causing deformation of the base 11, in one embodiment, a heat insulating sleeve 25 is provided at the bottom of the blending cup 2, and the limit groove 22 is provided on the heat insulating sleeve 25, which can effectively reduce the influence of the heat generated during use on the limit groove 22, and prevent the limit groove 22 and the limit ring 112 from deforming, thereby causing the gap between the blending cup 2 and the base 11 to be too large, affecting the stability of the blending cup 2 assembly, ensuring that the limit groove 22 and the limit ring 112 fit closely, and helping to reduce the occurrence of resonance during use. In addition, the heat insulating sleeve 25 can prevent the heated blending cup 2 from scalding the user, and ensure the user's safety in use, wherein the heat insulating sleeve 25 has a certain heat resistance and can withstand high temperatures during use.

[0041] like Figures 2 to 3 As shown, in order to further reduce the occurrence of vibration, in one embodiment, a shock-absorbing pad 13 is provided on the machine base 11, and the limiting ring 112 and the shock-absorbing pad 13 are an integrated structure. The shock-absorbing pad 13 can effectively absorb and buffer the vibration and impact generated during use, so that the machine base 11 and the mixing cup 2 are in flexible contact, reducing damage to the machine base 11 and the limiting ring 112, reducing the vibration of the mixing cup 2 group and the machine base 11, which is conducive to improving the stability and service life of the food processor. The limiting ring 112 and the shock-absorbing pad 13 are an integrated structure, which simplifies the overall structure, helps to reduce the number of parts, reduce production costs and assembly difficulties, reduce the direct effect of vibration and impact generated during the use of the food processor on the limiting ring 112, helps to improve the stability of the limiting ring 112, improves the limiting accuracy of the limiting ring 112, and helps to extend the service life of the food processor.

[0042] In order to further enhance the stability of the mixing cup 2 installed on the base 11, a cup body bracket 115 is provided at the bottom of the mixing cup 2, and the heat insulation sleeve 25 is fixed to the cup body bracket 115. The cup body bracket 115 is provided with a limiting convex surface that cooperates with the inner circle of the limiting ring 112 at intervals along the circumference. The mixing cup 2 is positioned in the circumferential direction by the cup body bracket 115 and the inner circle of the limiting ring 112. The limiting convex surface is pressed against the inner circle of the limiting ring 112, providing a more stable support and positioning effect, so that the center of the mixing cup 2 is aligned, reducing the resonance caused by rotational deviation, and enhancing the stability of the mixing cup 2. The cup body bracket 115 is arranged at intervals along the circumference, which can provide more uniform and stable support, and further ensure the stability of the mixing cup 2.

[0043] In order to further prevent the blending cup 2 from axially rotating relative to the machine base 11, in one embodiment, the limiting ring 112 is provided with a notch 1122, and the circumferential limiting structure on the machine base 11 is located in the same radial direction as the notch 1122. By arranging the notch 1122 and the circumferential limiting structure on the machine base 11 in the same radial direction, the blending cup 2 is limited at both ends in the same radial direction, and the blending cup 2 is limited in both the clockwise and counterclockwise directions of the circumference, thereby further reducing the rotation of the blending cup 2 and ensuring the stability of the food processor.

[0044] In order to achieve the transmission of electrical signals, in one embodiment, a coupler upper component 116 is provided at the bottom of the blending cup 2 between the limit groove 22 and the upper connector 21, and a coupler lower component 24 is provided between the limit ring 112 and the lower connector 111 of the base 11, and the coupler upper component 116 is electrically coupled to the coupler lower component 24. By providing the coupler upper component 116 and the coupler lower component 24, the connection between the blending cup 2 component and the base 11 is further strengthened, and a positioning point that is aligned with the upper and lower parts is formed, which is conducive to reducing the rotation of the blending cup 2 and can effectively reduce the vibration generated during use. In addition, the coupler upper component 116 is electrically coupled to the coupler lower component 24, which can achieve electrical coupling between the blending cup 2 and the base 11, realize the transmission of electrical signals, realize automatic and intelligent control, and realize precise control and monitoring of the blending process.

[0045] The blending cup body assembly is installed on the base 11, and the blending cup 2 is circumferentially positioned by multiple cup body brackets 115 and the inner side of the limiting ring 112, so that the blending cup 2 and the unit 11 are centrally aligned, wherein the offset gap between the cup body bracket 115 and the limiting ring 112 is 0.2mm, plus the tolerance, the maximum offset gap is about 0.5mm; at the same time, the upper connector 21 and the lower connector 111 are aligned and positioned up and down, and the coupler upper component 116 and the coupler lower component 24 are connected and positioned up and down to limit the blending cup 2, and the blending cup 2 is stably limited on the base 11 to ensure that the blending cup 2 cannot rotate at a large angle.

[0046] In the prior art, there is a certain gap between the upper coupler component 116 and the lower coupler component 24, so that the mixing cup 2 will rotate clockwise or counterclockwise at a certain angle with the upper coupler component 116 and the lower coupler component 24 as the fulcrum, and the deflection angle in the clockwise or counterclockwise direction will reach about 3°, and the offset distance between the upper connector and the lower connector can reach about 1.5mm, which makes the mixing cup component and the machine base poorly aligned, easily resonating, resulting in high noise. In the present application, the limiting boss cooperates with the limiting rib, so that when the mixing cup deflects with the upper coupler component 116 and the lower coupler component 24 as the fulcrum, the limiting boss and the limiting rib are limited, so that the deflection angle of the mixing cup is greatly reduced, so that the gap between the limiting boss and the limiting rib is generally not more than 0.3mm, the deflection angle is not more than 1.2°, and the offset distance between the upper connector and the lower connector is less than 0.3mm, which effectively reduces the resonance caused by the displacement of the mixing cup and effectively reduces the noise.

[0047] Among them, a circumferential limiting structure can also be set between the coupler lower component 24 and the coupler upper component 116. Specifically, a limiting boss 23 can be set on the coupler lower component 24, and correspondingly, a limiting rib 113 is set on the coupler upper component 116. The limiting rib 113 limits the limiting boss 23 on both sides of the circumference of the limiting boss 23. The limiting boss 23 and the lower connecting head 111 are located in the same radial direction, which limits the rotation of the stirring cup 2 and ensures the stability of the stirring cup 2.

[0048] Alternatively, the coupler upper component 116 is provided with a limiting boss 23, and the coupler lower component 24 is provided with a limiting rib 113, which is determined according to actual needs.

[0049] In order to further reduce the resonance caused by the offset between the base 11 and the blending cup 2, the circumferential limit structure position on the base 11 is located in the same radial direction as the lower connector 111 and the coupler lower component 24, and the circumferential limit structure position on the base 11 and the coupler lower component 24 are located on both radial sides of the lower connector. Specifically, the limit ring 112 and the shock-absorbing pad 13 are an integral structure, and a radial recess 1121 is provided on the limit ring 112. The radial recess corresponds to a circular arc concave shape, and limit ribs 113 are provided on both sides of the circular arc of the radial recess, and a lower guide slope 1131 is provided on the outer side of the limit rib. The coupler lower component 24 is close to the notch 1122, and the notch 1122, the coupler lower component 24, the lower connector 111, and the radial recess 1121 are located in the same radial direction, forming multiple positioning points on a straight line, which more effectively prevents the blending cup 2 from rotating relative to the base 11 and strengthens the circumferential rotation limit function. In addition, the two limiting ribs 113 are located on both sides of the radial recess in the circumferential direction. The two limiting ribs 113 are symmetrically arranged on the above-mentioned radial sides to further limit the rotation direction and rotation range of the stirring cup 2, ensure that the stirring cup 2 is tightly and stably connected to the base 11, and help reduce resonance.

[0050] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
